Hey Kristen,
Thanks for reaching out. We unfortunately don’t recommend any specific themes out there, though in general I would recommend the theme shop arraythemes.com — they make themes of excellent quality.
As for the specific layout you describe, I’m not sure about this. I’ve some folks use the Avada theme with this sort of layout to great success, so that may be worth looking into.
If your main concern is having 100%-width, you may actually be able to find this in most themes out there. The default WordPress themes, for example, include a “full width template” which you can use as the “Events template” for the “Events template” option in your site’s wp-admin. Many other themes out there include a full-width template; I would recommend inquiring about this from a given theme’s support team if you find a theme out there that you like.
Sorry that we don’t have many specific themes to recommend. I hope the information I’ve shared here helps you move forward in your search nonetheless.
Let me know if there’s anything else I can try to help with!
Sincerely,
George
